ISingleton, IFactory and IFunctionalTest base classes. TestFactory now use them. New arguments handling in main.

TestFresnelCoeff improved drawing of T,R fresnel coefficients for test samples, DrawHelper added drawing of sample

Provide clone for MultiLayer. MultiLayer now holds vector<Layer *> , i.e. pointers instead of objects.

New MaterialManager and updates in MultiLayer. Problem in LayerInterface exists (screwed pointers to layers).

On the way to add roughnesses of layers: new classes IRoughness, LayerInterface, lots of comments and const references. New Doc/Doxyfile for oxygen generation.

Added two unit tests for OutputData<T> class and implemented small changes in NamedVector and OutputData classes to improve usage.
